⚠️ Wildfire Smoke UK: The Threat
🌍 Increasing Frequency
European wildfires (Spain, Portugal, France, Greece) and rare UK moorland fires create smoke events affecting British air quality, particularly May-September.
☠️ PM2.5 Health Risks
Wildfire smoke contains PM2.5 particles that penetrate deep into lungs, causing respiratory issues, eye irritation, and aggravating asthma/COPD.
🏠 Indoor Infiltration
Smoke enters UK homes through gaps, vents, and open windows. Without filtration, indoor PM2.5 can reach 50-80% of outdoor levels.
⏱️ Multi-Day Events
Smoke events can persist 3-7 days when weather conditions prevent dispersion. Continuous HEPA filtration essential during alerts.
✅ How HEPA Filters Stop Wildfire Smoke
HEPA Filters Capture 99.97% of PM2.5
True HEPA filters (H13/H14) capture 99.97% of particles 0.3 microns or larger, including wildfire smoke PM2.5 (2.5 microns or smaller).
5+ ACH Provides Continuous Protection
Achieving 5-6 air changes per hour (ACH) filters room air every 10-12 minutes, preventing smoke accumulation during multi-day events.
